We are thinking of getting away for 5 weeks down to Spain in our motorhome. Just looking for sun. Have toured Europe before but only in summer months. Thought we would cross to Calais and follow previous advice from funsters on route down and through Vielha Tunnel. Weather forecast looks OK for going next week but a little bothered about the return via same route in the middle of February. I know we can't tell what the weather will be like then but has anyone any advice. How much time should I give for the return. can the roads be blocked, if so for how long?. We have 4-5 weeks. are we being daft?
